"Any person subject to military law who behaves himself with disrespect toward his superior officer...."

Unlike Article 62, disrespect toward a superior officer requires no words—acting or neglecting to act (such as rudeness or failure to salute) are enough.

Article 64.

Assaulting Or Willfully Disobeying Superior Officer:

Punishment: Death or court-martial.

  1. "Any person subject to military law who on any pretense whatsoever, strikes his superior officer—lifts a weapon, or offers violence against him, being in the execution of his office."
  2. "Or willfully disobeys any lawful command of his superior officer."
    Drunkenness here tends to show absence of the essential willfullness.
    Self defense is not forbidden nor violence to suppress mutiny.

Article 65.

Insubordinate Conduct Toward A Non-commissioned Officer:

Punishment: Court-martial.

  1. "Any soldier who assaults or attempts or threatens to strike or assault."
  2. "Or willfully disobeys the lawful order of a non-commissioned officer while in the execution of his office."
  3. "Or uses threatening or insulting language."
  4. "Or behaves in an insubordinate or disrespectful manner."
    Drunkenness will not have the effect here of showing an absence of willfullness.
